A concrete article reinforced with a ferrous material in said concrete article can be cathodically protected from corrosion by the application of a coating composite which can be applied, for instance, by thermally spraying a valve metal or alloy thereof together with a catalyst precursor compound onto a surface of said concrete article. Alternatively, the concrete article may be previously or subsequently coated with a catalyst precursor compound to form a separately layered anode coating. Conversion of the catalyst precursor compound to an electrochemically active catalyst occurs during thermal spraying or by the application of the thermally sprayed valve metal or alloy thereof over the previously applied catalyst precursor compound. Connecting the anode coating and the ferrous reinforcing material in the concrete structure to an electrical circuit and impressing a current sufficient to cause the ferrous material to act as the cathode in said circuit provides protection of the ferrous material against corrosion.
